Abstract

The majority of phycological studies in Turkey focus on seasonal changes of phytoplankton and phytobenthos in lentic and lotic systems, while very few studies related to counting diatoms in sediment cores obtained as a result of paleolimnological work have been published. In this paleolimlogical study, seventeen (14+3) n e w diatom records for freshwater algal flora of Turkey were determined on sediment core samples at five different locations collected in July 2006 from Lakes Ladik (Samsun) and Hazar (Elazığ). We recorded seventeen diatom taxa belonging to Naviculales (8), Cymbellales (2), Eunotiales (2), Bacillariales (2), Fragilariales (1), Tabellariales (1) and Aulacoseirales (1) orders from Lakes Ladik (Samsun) and Hazar (Elazığ). All of the reported taxa are new records for freshwater algal flora of Turkey. General information on the morphology and taxonomy of the species are briefly described in this paper, with their illustrations.

New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part IV: Ochrophyta

“…These records were mainly found in Susurluk, Sakarya, Fırat -Dicle, Yeşilırmak, Marmara, Doğu Karadeniz, Çoruh, Burdur, and Antalya basins. It has been seen that the contribution to new records is highest in Sakarya and Fırat -Dicle basins which have the largest surface area (Aysel et al, 1993;Öztürk et al, 1995a, 1995bŞahin, 2000, 2007, 2009Yağcı & Turna, 2002;Atıcı, 2002;Baykal et al, 2009;Sevindik et al, 2010Sevindik et al, , 2011Sevindik et al, , 2015Sevindik et al, , 2017Özer et al, 2012;Akar & Şahin, 2014;Yüce & Ertan, 2014;Varol & Fucikova, 2015;Varol & Şen, 2016;Maraşlıoğlu & Soylu, 2018;Şahin & Akar, 2019aŞahin & Akar, , 2019bMorkoyunlu & Aktaş, 2020). As a consequence of these studies, the total number of taxa have increased in Turkey (Taşkın et al, 2019;Maraşlıoğlu & Gönülol, 2020).…”

New Records for the Turkish Freshwater Algal Flora in Twenty Five River Basins of Turkey, Part III: Miozoa, Haptophyta

“…Due to the effects of four different types of climate, and noticeable altitude differences, Turkish lakes have different morphometry and hydrology that support distinct algal diversity. In recent years, many new records were given for the algal flora of Turkey (Aysel et al, 1993;Öztürk et al, 1995a, 1995bŞahin, 2000, 2007, 2009Yağcı & Turna, 2002;Atıcı, 2002;Baykal et al, 2009;Sevindik et al, 2010Sevindik et al, , 2011Sevindik et al, , 2015Sevindik et al, , 2017Özer et al, 2012;Akar & Şahin, 2014;Yüce & Ertan, 2014;Varol & Fucikova, 2015;Varol & Şen, 2016;Maraşlıoğlu & Soylu, 2018), and the total number of taxa have increased (Taşkın et al, 2019;Maraşlıoğlu & Gönülol, 2020). The present study aims to contribute to the algal flora of Turkey.…”
